Hardscape materials that sag on vertical surfaces should be a thing of the past with SRW Products' Vertical Instant Lock, an adhesive that creates a reliable bond in only a few seconds. The company says it eliminates the need for bracing, and allows materials to be applied without mortar. Vertical Instant Lock can be used with stone, block, brick, tile, metal, glass and wood, and the manufacturer says it can be used on stone pavers as heavy as 25 pounds. The adhesive should be applied in temperatures above 40 degrees. The manufacturer doesn't specify the type of adhesive used in Instant Lock, but information about its chemical composition and associated health warnings are available at the company's website.
